Shadow-Imprisoning Mirror

I have a fabled-raven and a fiend (atk 2500) on field and opponent have Shadow-Imprisoning Mirror face-up on their side of field. I activated raven effect to discard dark-world monsters to grave. Can I then chain Eradicator Epidemic Virus, call trap cards, destroy the mirror after I discard my cards and cont wif those dark world cards effect?

And IF you did tribute a DARK monster somehow with the mirror still on the field. Your Dark World monster effects would only activate if EEV is last in the chain. Meaning to say EEV *MUST* be last in the chain in order for the earlier Dark World effects to resolve.

Dear members,
Be sure to post a message once you have been registered. As I had just cleared 100+ member with no post in the forum. I am trying to keep the forum neat and tidy. Those users who just create an account to just come in to look and see, I am sorry but I have deleted the account. I would believe only the trading post is will be viewable to members so there should be a need for a guest to create an account to see what events we are having.

Also take note that TRADING THREADs are going to be auto prune everyday. Condition will be a post every 7 days else it will be deleted. Again its to keep neat and tidy in the forum.
